ASP.NET程序向Event Viewer写入Event Log

在web.config中的appsettings中写入

<!--Event Log--> <add key="EventLog" value="Application" /> <add key="EventSource" value="Project" />
在项目中global.asax中

protected void Application_Start(object sender, EventArgs e) { Log.Configure(Settings.EventSource, Settings.EventLog); }
在Log类中

public class Log { static string source; public static void Configure(string eventSource, string eventLog) { // Create the source, if it does not already exist. if (!EventLog.SourceExists(eventSource,".")) { EventLog.CreateEventSource(eventSource, eventLog); } source = eventSource; } public static void Error(string message) { Write(message, EventLogEntryType.Error); } public static void Error(string message, Exception e) { Write(message + "\n\n" + e.ToString(), EventLogEntryType.Error); } public static void Info(string message) { Write(message, EventLogEntryType.Information); } public static void Fatal(string message, Exception e) { Write(message + "\n\n" + e.ToString(), EventLogEntryType.Error); } static void Write(string message, EventLogEntryType type) { EventLog myLog = new EventLog(); myLog.Source = source; myLog.WriteEntry(message, type); } }
在Settings类中

public static class Settings

{ public static string EventSource { get { return WebConfigurationManager.AppSettings["EventSource"]; } } public static string EventLog { get { return WebConfigurationManager.AppSettings["EventLog"]; } }}

然后打开注册表

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application

创建一个新的key，key的名字就是项目的名字Project
